How to make simple machine lever model for school project | DIY first class lever working model

A lever is a simple machine that demonstrates the principles of mechanical advantage by reducing the effort needed to lift or move a load. In this tutorial, we’ll show you how to build a lever using simple materials like flat wooden sticks, super glue, spray paint, cardboard, marbles, and small empty bottles. This hands-on project is fun, educational, and perfect for understanding the science behind simple machines.

Materials You’ll Need

To make your simple machine lever, gather the following materials:

• Flat wooden sticks (5 pieces)
• Super glue
• Spray paint or acrylic paint
• Cardboard (for the base)
• A3-size sheet
• Marbles
• Small empty plastic bottles (to make buckets)
• A round wooden stick (lever arm)

Step to make Simple Machine Lever model

Step 1: Create the Wooden Stand

1. Take the five flat wooden pieces and assemble them into a stand as shown in the video.
2. Use super glue to stick the pieces together firmly. Ensure the stand is stable and well-balanced.
3. Once the stand is assembled, paint it using spray paint or acrylic paint for a clean and polished look. Let it dry completely.

Step 2: Prepare the Base

1. Cut a piece of cardboard large enough to serve as the base for your stand.
2. Stick an A3-size sheet onto the cardboard base using glue. This will provide a smooth and durable surface.

Step 3: Attach the Lever Arm

1. Take a round wooden stick (the lever arm) and cut it to a size of approximately 7×12 inches.
2. Add hooks to both ends of the stick to hold the buckets.
3. Attach one end of the lever arm to the top of the wooden stand, allowing it to pivot freely.

Step 4: Create the Buckets

1. Take small empty plastic bottles and cut them in half to create buckets.
2. Use super glue to attach sticks to the sides of each bucket, forming handles.
3. Hook the buckets onto the ends of the lever arm.

Step 5: Conduct the Experiment

1. Place the wooden stand on the prepared cardboard base.
2. In one bucket, place 18 marbles.
3. Gradually add marbles to the other bucket until the weight of 18 marbles is lifted. As observed in the video, only 5 marbles were needed to lift 18 marbles, demonstrating the lever’s mechanical advantage.

Understanding the simple machine lever Mechanism

A lever works by distributing force around a fulcrum (pivot point). The effort is the force applied to one end, and the load is the weight being lifted. By positioning the fulcrum closer to the load, less effort is needed to lift it, showcasing the principle of mechanical advantage.

Why Build a Lever Model?

This DIY lever model helps you:

• Understand Physics: Learn how forces interact to make work easier.
• Explore STEM Concepts: Engage in hands-on learning for students or enthusiasts.
• Develop Problem-Solving Skills: Experiment with weights and see how they affect balance.

Applications of Levers

Levers are used in many everyday tools and machines, such as:

• Seesaws
• Bottle openers
• Scissors
• Wheelbarrows

This simple project replicates how these tools work, making science both fun and practical.

Tips for Success

• Ensure the wooden stand is stable to prevent the lever from tipping over.
• Test different weights and fulcrum positions to see how the lever’s efficiency changes.
• Decorate the lever and base for a personalized and visually appealing model.

Conclusion

Creating a simple machine lever is an exciting way to explore the basics of physics and mechanics. By using materials like wooden sticks, super glue, spray paint, cardboard, marbles, and small plastic bottles, you can build a functional lever that demonstrates the principles of mechanical advantage.

This lever model is perfect for science experiments, school projects, or just a fun DIY activity. Try it yourself and discover how simple machines make life easier!
